Jérôme Pouiller 8bce06b06b staging: wfx: avoid possible lock-up during scan 
If the environment is noisy, the device may take time to send scan
requests. Thus, scan requests durations > 5s have already been observed.
During the scan, traffic is neither received, neither sent. From the
user point-of-view, the traffic is frozen for a long time.

This patch reworks the scan processing. It gives to the device a smaller
time budget than previously. However, it does not expect the scan to be
complete and it is able to send another scan request to finish the work.

A big part of the patch aims to avoid an infinite loop if the device
goes crazy.
